Hybridization is a bonding model, universally used in organic chemistry, which allows consideration of two-electron localized bonds in organic molecules. Without hybridization, it is almost impossible to describe aspects such as hyperconjugation for the stabilization of carbocations and alkane conformers. Hybridization is often presented in…

This article presents a theoretical-didactic perspective on the formation and development of concepts concerning mathematical objects as a result of research on didactic difficulties in dealing with concepts in school. The theoretical foundation that supports the research is based on the contributions of the materialist approach to the theory of…

An important element to doing mathematics and developing conceptual understanding in mathematics is creating and making sense of visual representations. Developing mathematical understanding happens when students invent (or reinvent) strategies and think deeply about why a strategy works. Although societal and political pressures may say otherwise…

A design-based research study on the development of one-page tools to support systemic thinking in public managers is presented. Study participants included public managers of social and human service agencies within government or nonprofit organizations, as learners for whom the tools were designed; and instructional design professionals,…

Cutting-edge technology enhances the teaching-learning process, with Multimedia-Based Instruction (MMBI) emerging as a powerful tool to achieve educational goals. MMBI creates visually engaging, resource-rich materials that support students in understanding abstract mathematical concepts, boosting interest and curiosity. According to Mayer (2001),…

The study of basic chemical reactions can be challenging for teachers in training when addressed in a lecture-based and out of context manner, lacking real-world examples, practical applications, or connections to daily life. Primary Reactions Race is a board game designed to help students learn basic chemical reactions such as oxidation,…

Teaching sports geography in higher education on the surface seems like it would be a great course to draw students in, get them exposed to geographic concepts, tools, and techniques, and the perfect forum for using examples to which students can relate. However, there are few instances of a sports geography course being in a regular rotation of…

We propose a simple computational model that describes potential mechanisms underlying the organization and development of the lexical-semantic system in 18-month-old infants. We focus on two independent aspects: (i) on potential mechanisms underlying the development of taxonomic and associative priming, and (ii) on potential mechanisms underlying…

In response to recent trends in the field of mathematics education, real-world contexts are frequently found in curricula and classrooms across the world. Numerous scholars contend that, in addition to making instruction more engaging and relevant, rich, imaginable contexts can provide a semantic grounding that helps students deeply understand…

Why do creative ideas and solutions to unresolved problems benefit from taking a break? The idea of unconscious work as an explanation is so appealing that even after reading this paper, which states clearly that unconscious work is a fantasy based on no clear theory and no clear empirical evidence, some readers will claim that we are saying the…

This paper discusses how geography's disciplinary ways of thinking can equip teachers "to organize deep geographical learning" about sustainable development in their students. These ways of thinking are based on the subject's core concepts, and the ones selected for discussion in this paper are environment, interconnection and place. The…

The problem here dealt with concerns physics education, and specifically the concept of force. The idea behind this research is that a historical approach to the teaching of such a notion is of great help for the students to fully understand the meaning of this basic physical magnitude. For, most of scientific concepts can be better grasped by the…

This paper aims to shed light on an overlooked but essential aspect of informal reasoning and its radical implication to mathematics education research: Decentralising mathematics. We start to problematise that previous studies on informal reasoning implicitly overfocus on what students infer. Based on Walton's distinction between reasoning and…

Professional learning may be the most significant when the teacher feels fundamentally challenged and questioned about their practices, beliefs, or identities. In this paper, the elements that cause such fundamental challenges and questions -- disruptions -- are called 'disruptive hooks'. In the process of addressing such disruptive hooks,…

How anthropomorphic reasoning functions in scientific thinking has been a controversial topic. There is evidence it is problematic as well as evidence it can play productive roles, for scientists and for students. In science education, however, the prevailing view remains that it is an impediment. For this study, we have chosen examples of what we…
